The dropped pin appears to be correct, going by the street view, which means the address to type into your GPS is 1469 White Pole Rd., Adair, IA. It's a mile and a half west down the road from 1156 Anita-Adair.
This is the address I will be trying this summer when I am out there. Wish me luck!
Very thought-provoking, whatever your stance on segregation may be. Definitely worth a visit. Not completely obvious on how to get there. Find more details here:

A good laugh while driving down 75, which you need because that highway is usually riddled with cops.
